ROLEX DAY DATE ROSE GOLD, SILVER DIAGONAL MOTIF REF. 228238

The Day-Date was the first watch to indicate the day of the week spelt out in full when it was first presented in 1956.The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic colour dials such as shades of silver grey, rhodium or ruthenium. Silver-plating is mostly used as a base layer for the sunray finish, where further colour is added to the prepared dial. Sometimes colours such as champagne are achieved through electroplating with more than half a dozen different metals.
